Sound waves could be the next big thing in fire-fighting technology. George Mason University engineering students Seth Robertson and Viet Tran have built a new kind of fire extinguisher that uses sound waves to extinguish fires as part of their senior research project – and it has a lot of potential to work in real world applications, both in everyday households and in outer space.
Samsung says it is "confident" it has solved the battery issues of its Galaxy Note 7 smartphone after multiple reports of the device overheating and catching fire and that the phone would go back on sale in the UK on October 28.
Space and the celestial atmosphere never cease to astonish and intrigue us. All kinds of strange scenarios if imagined in the space environment give super interesting results. Let’s imagine that you fired a gun in the space… then… you will think that it can’t be…. because fires can’t burn in the oxygen-free vacuum but add to this the fact that modern day guns come with their own oxidizer. So now you have shot a bullet in the space and then what happens? There can be different interesting scenarios in this.
Teenage rebellion takes many forms. Some of us get dumb haircuts or listen to some truly terrible music. But for the amateur scientist, breaking your mother’s heart* involves diethyl ether and the family pool.
The thing about deithyl ether is that it’s really, REALLY flammable. And it floats on water. So The Backyard Scientist set out to determine if said fire could lit in a swimming pool, and then be extinguished by liquid nitrogen. Because liquid nitrogen also floats on top of water it creates an oxygen barrier that puts out the raging flames. For a bonus experiment he also attempts the same feat but with dry ice instead of liquid nitrogen. Granted, he also briefly sets his hand of fire in the process.
Video games are sold on hyperbole. From gruesome, over the top trailers for gory first-person shootersto breathtaking, to picture-perfect explosions in open-world action-adventure games, there's very little that's grounded in reality. If there aren't monsters to slay or dictators to dethrone, there's a conspiracy to unearth or revenge to be had.
